Объяснение:
[tex]a^{5}[/tex] · [tex]a^{-2}[/tex] = [tex]a^{5+(-2)}[/tex] = [tex]a^{3}[/tex]
[tex]\frac{b^{5} }{b^{-2} }[/tex] = [tex]b^{5}[/tex] : [tex]b^{-2}[/tex] = [tex]b^{5-(-2)}[/tex] = [tex]b^{5+2}[/tex] =[tex]b^{7}[/tex]
[tex](a^{-2}) ^{-3}[/tex] = [tex]a^{(-2)*(-3)}[/tex] = [tex]a^{6}[/tex]
